In this investigation the stir casting technique is utilized to fabricate Al2024-B4C nano composites. The nanoB4C particles used in the reinforcement material have a particle size of 50 nm and variable weight percentages. In Al2024 composites, boron carbide reinforcement is included at weight percentages ranging from 0% to 3%, with a 1% interval between each percentage addition. Following the casting process, the samples were prepared for microstructural and mechanical evaluation in accordance with the standards established by ASTM. Scanning electron microscopy, often known as SEM, is utilized for the purpose of analyzing the distribution of nanoparticles inside the matrix material as well as for the purpose of examining the morphology. As can be seen in the scanning electron microscope (SEM), there is a consistent distribution of nanoparticles across the entirety of the matrix, and there is a reduced amount of porosity that is left over. Stir casting with vacuum assistance is an effective method for producing aluminum composites because the reinforcement is distributed evenly throughout the casting process. In comparison to other samples, the composite Al2024 that contains 2 weight percent nB4C demonstrates superior mechanical capabilities. These properties include its hardness, tensile strength, compressive strength, and impact strength scores. In nano particle-added composites, the hardness, maximum tensile strength, compression strength, and impact strength were measured to be 88 HV, 320 MPa, 511 MPa, and 25 J/cm2 respectively.

Keywords: Aluminium composite, Boron carbide, Nanoparticles, Tensile strength, Vacuum-assisted stir casting.
